Water block Thermaltake Pacific W1

Thermaltake Pacific W1 CPU Water Block is a compact copper water block engineered for custom PC liquid-cooling loops. It features a full copper base with nickel plating, 0.15 mm internal micro-channel fins and a mirror-polished CPU contact surface to provide efficient heat transfer and corrosion resistance. The unit is Tt LCS Certified and designed to support a wide range of modern Intel and AMD CPU sockets while keeping a small footprint and a black finish.

Advantages

The copper base with anti-corrosive nickel coating and a mirror-polished mating surface ensures reliable thermal conductivity and long-term protection against corrosion. The optimized 0.15 mm micro-channel fin structure and silicone guide rod improve coolant flow and enhance heat dissipation in compact form. A universal mounting mechanism enables tool-free, error-reduced installation across supported CPU sockets.

Suitable for

• Custom PC liquid-cooling loops
• High-performance desktop CPU cooling
• Compact and modular chassis with limited clearance

Key specifications

How to use

Mount the Pacific W1 onto a compatible CPU socket using the included universal mounting mechanism, following the manufacturer’s mounting orientation and tightening sequence to ensure even contact. Apply a thin, even layer of thermal interface material to the CPU heatspreader before installing the block. Connect inlet and outlet tubing to the water block’s fittings and verify coolant flow through the micro-channels; bleed the loop of air and ensure leak testing before powering the system.

Recommendations

Use corrosion-inhibited coolant and follow periodic maintenance: inspect for deposits, replace coolant according to the coolant manufacturer’s guidance, and verify mounting torque after system transport or significant thermal cycles to maintain optimal thermal performance.
